PORTABLE SPRAYER.

' Application filed January 1 To all'whomz'tmag concern: 7

'Be it known thatI, WAITE W. KEENE, a citizen of the United States, and a resident of Quincy, .in the county of 'Norfolk and Commonwealth of Massachusetts, have in vented certain new and useful Improvements in Portable Sprayers, of which the following is a specification. This invention relates to 10 ers, andparticularl ing-floors with oil.

In such sprayers, it is desirable that the mechanism for operating the discharge valve be disposed forconvenient manipulation by the same hand with which the user carries" the supply tank, leaving the other hand of the user free to operate the pump from time to time to maintain a pressure of air upon the oilor other liquid within the tank.

According to my invention, the tank is provided with a vertically slotted carrying handle and the discharge valve is opened by direct upward lift upon a spring-tensioned portable sprayy to a sprayer for spraypull stem which isoperatively connectedat oneend' with said valve and at its otherend is bent to provide a. finger hook 'disposed through the slot of the carrying handle soas to lie under the cross bar of said handle' conveniently within reach of the same hand with which the user grasps said handle. This arrangement not only provides a simple, positive and conveniently operable actuating mechanism by which the valve may be opened and held open with the minimum of effort as the user carries the tank over'the-fioor, but permits the valve and spraying nozzle to be located beneath the tank bottom at substantially the edge thereof.

Another feature of my invention consists in the combination with a spraying nozzle so located, of a supporting base depending from the tank bottom a skirt or shell and provided opposite the dis charge nozzle with an outlet opening through which the oil may be discharged from said nozzle outwardly over the floor.

These and various other features of ad-' vantages which will appear more fully here inafter are secured'in the device of the presof the forefinger s an annular enclosing" I pipe 6.

Throughout the specification? and drawings like reference characters are cor respondingly applied, and in the drawings; Figs. v1 and 2 are elevations at rightan gles to each other of a portable sprayer in accordance with myinvention.

Figs. 3 and 4 are plan and side views respectively of the spraying nozzle and per, ticularly showing t discharge valve. p t

F ig.-4 is a section on the linedt of Fig. 4.

Figs. 5 and 5 are detail views showing-a] 'modified form of connection between'the finger-operated pull stem and the rocker arm-for the discharge valve.

Figs. 6, 7 and 8 are detail'views showing a modification of the guide for the'p'ull-stem. Fig. 7 being a section onthe line 7Tof, Fig. 6, and 2 Fig. 9 shows a'further modification ofthe connection detailed in Figs. 5 ands.

I have indicated at 1 a portable tank of suitable :ca drical for pendin from the tank bottom as anannular enc osingskirt or shell which is prefer ably cut out between its ends, as indicated at 3, to provide an on front. of the tank throu ing nozzle 4 of the tan the liquid expelled t discharge port 5 of s tributed outwardl onto the floor.

k is exposed whereby hrough the elongatedv aid nozzle may be disis disposed beneath the tank bottom at substantially the center thereof, and is connected with the int Rotatable within the nozzle upon journals 1 7 Figs. 3 and 4, is

recess 1 communicating with the pipe 6 and YOUNG COM- I he rocker arm for the so i pacity and preferably of cylin 1 m, and at 2 a supporting baseffdetlet opening at the gh which the'spray y through said opening I As appears inFigs. land 2, the nozzle erior of the tank by a supply a valve plug 7 having a a discharge passage 7 leading from said recess and adapted to connect with the discharge port 5 of the nozzle to establish and destroy the communication between the pipe 6 and the port 5, according to the position of the valve.

Fast to the valve at one end thereof is a rocker arm 8-which is bent upon itself to extend along the nozzle to substantially a. point opposite the pipe 6, Fig. 3, and thence outwardly at right angles. In Figs. 1 and 2, the outer end of the arm 8 is shown as perforated to receive the lower end of a pull stem 10 by means of which the valve is opened and closed.

In the modification shown in Fig. 3, the outer end of said arm is bifurcated to provide a slot 9' within which the lower end of the stem 10 is slidably engaged.

In the modification shown in F igs. 5 and 5, the sides of the stem 10. are reduced for a portion of their length to leave an intermediate web 11 which is disposed in the open-ended slot 9 of the arm.

In the modification shown in Fig. 9, the arn and stem are connected by a pin and slot 12.

The pull stem 10 extends vertically along the side of the tank and terminates at its upper end in an inturned finger hook 10 by means of which the stem may be raised to open the valve against the action of spring 13 coiled about said stem. At its lower end, the spring abuts a collar 1% pinned to the stem and at its upper end bears against a guide which in the form shown in Figs. 1. and 2 is a simple angle iron comprising horizontal basal portion 15 through which the stem is passed and a vertical side portion 15 extending from the outer edge of said horizontal portion and terminating in an inturned horizontal fiange 15 Fast to the top of the tank is a carrying handle 18 comprising spaced attaching portions and a horizontal cross-piece connecting said portions. The outer attaching portion of the handle is slotted longitudinally, as indicated at 19', and the inturned hook end 10 of the pull stem is entered through said slot and lies under the cross-piece of the handle so that the forefinger of the hand which grasps the; carrying handle may be laid under said hook end and the pull stemraised to open the valve by simply crooking the finger.

hen the pull stem is raised to open the valve, the spring 13 is con'ipressed. lVhen said stem is released. said spring expands to return the stem and rocker arm to normal position, thereby positively closing the valve. The upward movement of the stem is limited by the abutment of a stop 29 thereon with a set screw 30 which is mounted for vertical adjustment upon the flange 15 of the guide 15', and the downward travel of said stem is limited by the abutment of said stop with the basal portion of the guide.

As an alternative construction, the guide 15 may be formed as detailed in Figs. 6, T and 8 wherein said guide is shown as forked to straddle the web of an attaching lug 16 which is soldered to the tank wall, the guide being fastened to the web by rivets 17. lVith this construction, the finger pull may be entered laterally through the slot 19 of the carrying handle, as indicated by the arrow in Fig. 8, in assembling the device, and moreover, the upper end of the slot itself serves as a stop to limit the opening of the valve.

The hand pump of the tank is indicated at 34C and the tunnel for the filling opening at 35.

Various other modifications may obviously be resorted to within the limits of the ap pended claims.
